High-density hardware and software are developed as part of an initiative to greatly increase data center compute densities. Concept systems presented here are based on the Intel® Itanium™ processor family and are designed for a 1U rack-mount form factor. The current dual-processor system concept is targeted at the front-end server market (e.g., web hosting and mail routing), … [Read more...]
EMC and Thermal Design Conflicts in a PC
Thermal and EMC design in high-speed digital electronics systems has become a battle of conflicting requirements. Faster switching has led to increased electromagnetic (EM) emissions due to the extended bandwidth of signals. Higher-density components are consuming more power, generating increased EM fields and more heat. Electronics equipment must comply with radiation limits … [Read more...]
Electroosmotic Microchannel Cooling System for Microprocessors
Computer heat sinks, such as fin arrays and heat pipes, are much larger than silicon chips and are continuing to grow in size. This trend is driven by the increasing chip heat generation rates and has serious implications for overall system performance. The large volume of existing heat sinks causes discrete memory, video, and power-delivery components to be crowded away from … [Read more...]
Electronic Information Exchange
Electronic data exchange represents a very important link for integrating PCB electrical layout, analysis and mechanical design. It has become, in fact, the basis for enhanced economic and industrial growth. The Intermediate Data Format (IDF) is the most used file format for exchanging printed circuit assembly (PCA) data between electrical and mechanical CAD/CAE systems and for … [Read more...]
Thermal joint conductance for graphite materials
The heat flow across a metal/interstitial elastic-layer/metal joint is a very important problem in many microelectronic applications. It is generally known that when two surfaces are brought together, intimate solid-to-solid contact occurs only at discrete parts of the interface. Therefore, the actual contact area of pressed surfaces represents a very small fraction of the … [Read more...]
